you must choose any one power you know that targets one creature and which is not a ray or touch power,

and you must select a favored energy type (fire, cold, acid, electricity, or sonic).

When you maintain your psionic focus, the power you designate is psionically spiked with your chosen energy type and so deals +1d6 points of the appropriate type of damage in addition to its normal effect —if it takes effect.

Special: You can take this feat multiple times. Each time you take it, it applies to a new power you know.
